Hi all!
I'm a math student at the first year of my degree. To begin, sorry for my poor English, it's purely academic. I have a teacher of "Partial differential equations", who gave me exercises named "Exercises of locally convex spaces". All of this without any theory behind it, and I don't really know how to begin with them, since he won't help us and he doesn't reply to our mails. Could anybody give me some hint? Thanks in advance, I'll appreciate any help.
I have to show with explicit examples that the space C(A) of continuous functions in the open set A in R^(n) contains bounded sets that for the compact-open topology are not bounded.
Thank you all :)
Anyone know a good one? Everything I've tried to read assumes way too much background. I'm solid in point-set topology, linear algebra and basic functional analysis, but I don't know what a bornology, a fundamental system of convex neighborhoods, or a filter is.
I had 2nd surgery tuesday. Changed back today only to find there's no room between new stoma and skin. Nurse is telling me i need deep convex barriers. I ordered from edgepark but they won't be here until Monday or Tuesday. is there any where locally in LA i could pick some up? All i have is light convex and flat ones. Thanks!!
Hi all. Prior to the 9.0 update any files I deleted from a locally connected USB (deleted from another machine via SMB) would show the free space immediately. Now, since 9.0 anytime I delete a file it doesn’t show the free space asa available until after a reboot (eg I delete 100GB it will not make that empty space available until after I reboot.) Any ideas what I can do to rectify this? Thanks in advance.
Let E be a normed space, (X,d) a metric space and A ⊂ E a convex bounded set. Let f: A → X be uniformly continuous. Show that f(A) is bounded.
I have been struggling with this question for days now and I cannot figure out how to prove it. It doesn't seem to follow the regular epsilon-delta manner. Any help would be appreciated. By convexity of A I have that for any x,y \in A, also kx + (1-k)y \in A and by boundedness of A I have that for any x,y \in A |x-y| <= M.
With a new phone and the holidays coming where lots of photos will be taken, I want to make sure what I'm planning on doing is sound.
I have Google photos set to upload at the space saver setting. However, I want to keep the original quality locally on my phone. I'll let Google photos do its thing syncing photos all the time and maybe twice a year I plan on manually backing up the original quality photos to some hard drives and deleting the local copies to make space in my phone.
My concern is that since Google photos is my main photo app, is it automatically converting all my pictures to space saver every time it syncs? I'm hoping it's just the copy that is uploaded and the local copy stays untouched.
I've checked and can't find a satisfactory explanation online. I see a lot use of the phrase along with "spaces", topological or otherwise. I came face to face with that term in the phrase, "a locally convex curve".
My understanding so far: locally, the "thing" is convex but over the whole, it's not or doesn't have to be. So, no loops and/or the curvature never changes sign? But then, what's that mean? Examples would be helpful!
Thanks.
I know of bdb but does that work for the rss solar system I also know of tundra which ads the space x rockets but also don’t know if that would work or be accurate, so my 2 questions are simple 1. Do bdb and tundra work for rss(has accurate fuel) 2. If not what are the mods that add these rockets for rss.
Anyone have a decent source for a nice convex 1u space key? The lip on my current blank is leaving a divot in my thumb. Maybe this is how we identify each other IRL, by our weird thumb callouses?
I'm heavily invested and just wanted to get out of echo chambers for a bit. Anyone sees any downsides or red flags?
I've been the TD of a small-ish venue for a few years now but we do get a few internationally touring shows per year, and it seems like here in North America we're just really different from everyone else in the equipment we use and the way we work. My venue is all S4 fixed lekos and PARs, no fresnels (the original TD didn't believe in them, and I have no space to put them anywhere even if I had an opportunity to buy). This sucks because every rider comes in wanting zooms and fresnels. But sometimes I get requests for PCs, and since international groups sometimes aren't the easiest to communicate with in English, I have trouble asking what they actually mean by this, so I'm forced to try to use the plot symbol and wattage to try to interpret.
I know we're talking about PARs if they specify MFL, WFL, cp61, cp62, etc. but often they don't. Just a few days ago I got a rider asking for 20 650W PCs. I don't even think anyone supplies 650W PAR lamps in my city. Does that mean they're asking for 650W Plano-Convex spots? I don't even think those exist in my city either. The symbol looks like a fat rectangle with barndoors. Does anyone even use Plano-Convex spots anymore?
Are there any Europeans here that can help me figure out what I'm being asked for? I can't exactly Google "PC" and get a great result...
How strongly supported is the conjecture? It seems like if the remaining Arch. solids were Rupert our computers could find it.
